Quote by Walter Brower
The wolf was sick, he vowed a monk to be: But when he got well, a wolf once more was he.

Summary
This quote illustrates the notion that true nature or habits cannot be easily changed or suppressed. In this case, the wolf temporarily assumes a different identity as a monk due to his illness. However, once he recovers, his inherent instincts return, and he reverts to his original predatory nature as a wolf. It implies that one's innate qualities or characteristics cannot be indefinitely altered or ignored, emphasizing the intrinsic nature of individuals that cannot be easily modified.
